Protein’s solubility depends on the relative balance between protein-solvent and protein-protein interactions.

Protein’s solubility depends on the relative balance between protein-solvent and protein-protein interactions. Correct Answer True

Every protein has a different solubility and it is a relative balance between the protein-solvent and protein-protein interactions. The former causes the protein to remain in solution, and the latter causes it to aggregate.

Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.

An alternative approach to determining protein–protein interactions is to use a large-scale affinity purification technique that involves attaching fusion tags to proteins and purifying the associated protein complexes in an affinity chromatography column.
Assertion (A): In preparing final accounts, if closing stock is given in the trial balance, it is shown only in the Balance Sheet.
Reason (R): Any item appearing in the trial balance is treated only at one place i.e. either in the trading and profit & loss a/c or in the balance sheet.
